Abstract: 708,707. Hypodermic syringes. STERLING DRUG Inc. Oct. 27, 1952 [Nov. 1, 1951], No. 26904/52. Class 81(2) A disposable hypodermic syringe comprises a synthetic resin one-piece ampoule 10 having an open end 12 in which a plunger 20 is located, a closed end in the form of a diaphragm 18 and an open-ended tube 16 extending beyond the' diaphragm. A doubleended needle 24 is firmly mounted in a slidable needle guide 22 and placed with its inner end 26 adjacent to the diaphragm 18, the needle then being enclosed by a tubular cover 30 which is a sliding fit within the tube 16. When the syringe is required for use, the cover 30 is first pressed inwards so as to move the guide 22 and needle 24 downwards, thus causing the needle to pierce the diaphragm, the cover is then withdrawn and its end 34, which is threaded, is screwed into a recess 38 in a plunger 20 to expel the contents.

Title: Treatment of waste fibrous materials of synthetic origin
IPC: D06M11/11
Filed: 1947-10-10
Abstract: Waste fibrous nylon is treated with a degrading solvent, viz sulphuric, hydrochloric and formic acids, to destroy its filamentary nature, the degraded polymer being precipitated from the resultant mixture or solution to give a powder.  Silk fibre may be added to the mixture or solution to obtain particles coated with silk fibroin.  In examples: (1) nylon waste is treated with dilute H2SO4 and the solution is diluted with water to precipitate spongy granules which are washed and dried; (2) nylon waste is treated with boiling dilute HCl, silk fibre is added and an alkaline oxidizing solution is added to give a precipitate; (3) nylon waste and silk waste are dissolved in 80 per cent sulphuric acid, the mixture being reacted with a higher fatty alcohol such as stearyl alcohol and neutralized with alkali to give a product containing a precipitate which may be used as an emulsifier to make ointment bases.  The products may also be used in the manufacture of semi-abrasive detergents, wetting agents, shampoos, soaps, face powders, toilet creams, dentifrices, and as a vehicle for drugs, dyes and antiseptics.  Specifications 544,715 and 563,078 are referred to.

Abstract: 1501652 Washing - machines ENGELHARDT & FORSTER 22 Jan 1975 27497/77 Divided out of 1501651 Heading D1A A continuous laundry washing machine comprises a horizontal, rotatable apertured drum 3 within a casing 1, both the interior of the drum and the gap between drum and casing being divided radially into chambers by partitions 9a, 9b etc. which project outwardly of the drum and make a fluid tight seal with the casing which is also preferably composed of segments 16a, b, c etc., the partitions 9 being formed with an aperture and the chamber within the drum, having conveyors 27a, b, c etc., so that batches of laundry may be advanced along the drum through different baths in the respective chambers. The drum is supported and driven (oscillated for washing and rotated to advance the laundry) by belts 13a to d etc., driven in turn by an electric motor 19 via a shaft 14. The belts also serve to make said fluid tight seal. The drum rests on the floor of the casing when not in use and is raised by pneumatically-operated jockeys 26 which tension the belts, the drum height being set automatically with height sensors, this system also compensating for changes in the loading of the drum. The chambers formed between the drum and casing are supplied independently with liquids by pipes 34 and a control box 36. The drum may comprise a soaking chamber(s), prewash chamber, washing chamber(s) at different temperatures if required, hot and cold rinse chambers. The conveyors comprise a portion 29 formed as a segment of a circle curved into a helical shape and triangular portions 31, 32 feeding a sectorshaped aperture 28 in the adjacent partition.

Abstract: 1,156,952. Automatic exchanger. NETHERLANDS POSTAL & TELECOMMUNICATION SERVICE, DIRECTOR GENERAL OF. 15 June, 1967 [20 June, 1966], No. 27606/67. Heading H4K. In a telephone system one out of n possible v.f. signals is discriminated by counting the number of cycles of the signal arriving within a predetermined period. The v.f. signal essentially sinusoidal is converted into a square-wave signal which drives a first counter having a counting cycle of which the n frequencies are whole number multiples. A second counter counts the number of cycles performed by the first counter and thereby indicates which of the n frequencies has been received and which is exhibited by lighting one of n lamps. Whilst retaining the second count the first counter is returned to normal and exposed to the v.f. signal to see by not being driven off-normal whether or not the signal has ended. This is repeated until the signal has ended, the counting capacity of the first counter being increased for this stage. When the signal has ended both counters are returned to normal in readiness for the next v.f. signal. The first counter may step-on the second at the end of its counting cycle, or at some intermediate count to thereby shift the detectable frequency band.

Title: Improvements relating to electric cables with extruded insulant
Inventor: WHITE FRANCIS THOMAS
IPC: B29C48/06
Filed: 1962-07-18
Abstract: 967,567. Extruding cable sheathings. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 11, 1963 [July 18, 1962], No. 27607/62. Heading B5A. [Also in Division H1] Electric cables are sheathed by concurrently extruding around the cable, a semi-conductive, an insulating and a further semi-conductive layer in that order, using a single extrusion head, the material for the semi-conductive layer being such that the layers may bond with the insulant material layer to give complete and intimate contact. Insulant material from an extruder (not shown) passes via inlet port 22 through port 24 and shaped channel 28 to be extruded through orifice 18 whilst semi-conductive material from another extruder passes through inlet port 21 and then splits, part going via channel 27 to be extruded through orifice 16 and the rest through ports 23, 25 and channel 29 to be extruded through orifice 20 in this way forming semi-conductive layers, inside and outside the insulant layer, all around the cable which is passed through the extrusion head in the direction of the arrows. The extrusion head is constructed of four interfitting tip and die units 10, 11, 12, 13 shaped and connected to define the annular orifices 18, 20, 19 and material feed channels 27, 28, 29 which are shaped so as to distributively feed the materials to the annular orifices 18, 19, 20. The tip and die units are maintained in alignment by keys 26 in suitable keyways. Modifications of the tip and die units to form various shaped channels 27, 28, 29 are described. The method may be used for coating non-circular cores by extruding the semi-conductive and sandwiched insulant layers, as a tube around the core, and then drawing it down around the core by applying a degree of vacuum to the back of the extrusion head. The insulant material used may be a poly-olefine and the semi-conductive material a poly-olefine with or without a modifying synthetic rubber, loaded with finely divided conductive material.

Abstract: 959,304. Releasable fastenings. CLEMCO AREO PRODUCTS Inc. July 31, 1961, No. 27664/61. Heading E2A. [Also in Division F1] Means for locking relatively reciprocable members comprises a bevelled shoulder on one member co-operating with a bevelled segmental locking dog constrained to radial movement only with respect to the other member and movable into, and out of, the locking condition by toggle link means. The piston 2, of an hydraulic jack, working in a cylinder 1 carries segmental locking dogs 3a, 3b in circumferential grooves 23, the dogs being bevelled in the direction of piston movement complementary to bevels 14 on the ends of the cylinder bore. The dogs are constrained to radial movement only by a guidance member 6, having radial faces 61 engaging radial stems 32 on the dogs, secured to the end of a servo piston 53 which has a toggle fulcrum 5 carrying toggles 4 to impart radial locking movement to the dogs under the action of a spring 51. The application of hydraulic pressure to one end of the cylinder, as through inlet 13b, moves the servo-piston 53 against spring 51 to allow collapse of the toggle 4 and retraction of the dogs under the action of the bevels 14, 14b as the piston 2 moves under the action of the pressure; the space 25a behind the servopiston being vented at 22 to the low pressure side of the piston 2. When the piston reaches the end of its stroke the spring 51 together with pressure behind the servo-piston causes the toggles 4 to move the dogs to the locking position. In a modification the dogs are constrained to radial movement by dowels and are moved by wedge members forced between their bevelled ends by toggle links. Reference has been directed by the Comptroller to Specification 763,956.
